SAW-TOOTH SHAPER.

Specification of Letters Patent.

Patented Jaw, 1913.

Application filed January 10, 1912. Serial No. 670,529.

To all whom it may concern:

Be it known that we, EDWIN J; LUKE- MEYER, a citizen of the United States, and resident of Helena, in the county of Phil lips and State of Huntingburg in the county of Dubois and State of Indiana, and WILLIAM GEIB, a citizen of the United Cloverdale, in the county of Barry and have invented certain and we do herebydeclare Tooth Shapers;

be a'full, clear, and exact the following to -description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toimprovements in saw tooth shapers for saws, and has foran object the arrangement of improved means by which swagedfteeth may be equalized and correctly shaped.

Another object of the invention is the arrangement of a shaper for swaged teeth comprising an adjustable body portion and portion formed with ways the angle of a file used in shaping the teeth being operated upon.

With these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully dea tooth engaging for determining scribed and claimed.

In the accompanying drawings: Figure 1 1s a fragmentary side view of a saw wlth an embodiment of the invention applied thereto. Fig. 2 is an edgeview of the structure shown in Fig. 1. Fig. 3 is a top plan view of the structure shown in Fig. 1. Fig. 4 is a perspective view of the shaper shown in Fig. 1. Fig. '5 is a fragmentary view of a slightly modified form of the invention, the same showing an adjustable head. Fig.

I 6 is a top plan view of the structure shown in Fig.

Referrin to the accompany ng drawlngs by numera s, 1 indicates a saw formed with teeth 2 adapted to be swaged. After the teeth 2 have been properly swaged it is necessary to go overthe same and sharpen the teeth and otherwise shape the same so that the teeth will be approximately the same size. Several means have been pro.-

5 'vided for) accomplishing this result and several methods utilized, but according to the present invention a shaper '3 is used Arkansas, formerly of States, and resident of of the respective teeth,

' of the teeth.

formed with a body portion 4 accommodating a plurality of adjusting screws 5. .The adjusting screws 5 are adapted to hold the body 4 at any desired distance from the saw 1, and to properly adjust the head 6so that.

the center of the same will register with the center of the saw 1. Body 4 is bent and somewhat reduced at point 7 fromwhichit merges nto head 6. Head 6 is formed sub-.

sents beveled sides 8 "and 9 which act as guides fora file used in filing the sidesfof the teeth 2. A notch 10 is formedin head. 6 foraccommodating the edge or the point p so that the sides thereof will fla're outwardly'on each side of the center line of head 6 and in a positionto be engaged by the fileas the same is moved back and forth acrossthe beveled or inclined surfaces 8 and 9. Extension 11 is also provided for assisting in guiding the i saw; a

In operationthe saw 1 is swaged in any desired manner. It will be evidentthat the saw 1 may be of the circular varietyor an ordinary straight saw or any other kind of. saw as desired. After the saw 1 hasbeen swaged theshaper 3 is placed thereon and then the screws 5 are moved until the shaper is adjusted so thatthe center of the .head 6 will come opposite the center of the saw. Then a file is used for shaping the sides After the first tooth has been properly shaped the shaper is moved to the; next tooth and from thence to the next succeeding tooth. This action is continued until all of the teeth have been properly shaped. In Figs. 5 and 6 is disclosed a. slightly modified form of the invention in which the head 6 is divided into a rigid portion 12 connected preferably integrally with the body portion 4, and an adjustable. portion 13 adjustably connected with the bodyportion 4 and the rigid portion 12. The movable or adjustable portion 13 is formed with an inclined side portion 9 and a file guiding portion '11, together with'a notch 10 registering wit-hnotch 10. Adjustable or movable portion 13 is formed with an upper end 14 having a slot 15 formed therein through j which passes a clamping bolt16. Thelower part of the movable portion 13 is formed with anenlargement 17 andan extension 18. 1

The enlar ementl'r'isada ted to accommo a V P v date a clamping screw or bolt 19 which enters a suitable threaded aperture in the body 1 for drawing the movable portion 18 toward the rigid or stationary portion 12, the same being guided in its movement by extension 18 and upper end 14. Extension 18 also acts as a brace for stiffening the movable portion when the shaper is in use. Preferably there is only one bolt or screw 19 for drawing the movable portion toward the rigid portion, but there are preferably a plurality of bolts or screws 20 passing through the upper end of body 4 and pressing against the enlargement 17 for spreading or moving away the movable portion 13 from the rigid portion 12 for causing the head 6 to properly fit a large tooth. It will be noted that the bolts or screws 20 are used for separating the parts of head 6, while bolt or screw 19 is used for drawing the parts together. These bolts, together with the clamping bolt 16, hold the movable portion firmly in any of its adjusted positions.

In practical operation either a shaper formed with a solid head as disclosed in Figs. 1 to th may be used, or a shaper formed with an adjustable head. The adjustable head 6 disclosed in Figs. 5 and 6 may be used on various sized teeth within certain limits with the same advantage as is disclosed or provided for in the solid head.

What we claim is:

1. In a saw tooth shaper, a plate, means carried by the plate for adjustably disposing the plate upon one side of and relative to a saw, a head member carried by the plate and adapted to be positioned at the point of the tooth of the saw and provided with a depression proportioned to receive such tooth extremity, the sides of said head being tapered from opposite directions to form a guide for dressing the sides of the saw tooth.

2. A saw tooth shaper comprising a plate adapted to be spaced away from a saw and located in a plane parallel thereto, with means for adjusting the interval between the plate and the saw, a head carried by the plate comprising a notch positioned to receive the point of a saw tooth, said head being also provided upon opposite sides with tapered guides converging toward the side provided with the notch and serving as guides for an implement employed is dressing the sides of the tooth.

3. A saw tooth shaper comprising a plate, means to position the plate relative to the side of a saw, a head carried by the plate, a depression formed in the head adapted to receive the point of a saw tooth, said head being laterally expansible and provided upon opposite sides with guide surfaces converging toward the depression and adapted to serve as guides for the implement employed in dressing the sides of thetooth.

In testimony whereof I affix my signature in presence of two witnesses.
